Abstract

A technique of jamming a victim radar includes digitizing an incident waveform received from the victim radar and convolving the digitized waveform with contents of a range trace memory. The range trace memory stores a sequence of impulses, which, when convolved with the digitized waveform, creates a corresponding sequence of delayed versions of the digitized waveform, one for each impulse in the sequence, and adds together the delayed versions to produce a single output signal. The output signal is then converted to analog form and transmitted back toward the victim radar.

Abstract

Techniques involve releasing and/or capturing a fixed-wing aircraft (22) using an aerial vehicle (24) with VTOL capabilities while the fixed-wing aircraft (22) is in flight. For example, the vehicle (24) may take off vertically while carrying the fixed-wing aircraft (22) and then fly horizontally before releasing the fixed-wing aircraft (24). Upon release, the fixed-wing aircraft flies independently to perform a mission. After the fixed-wing aircraft has completed its mission, the vehicle may capture the fixed-wing aircraft while both are in flight, and then land together vertically. Such operation enables the fixed-wing aircraft to vertically take off and/or land while avoiding certain drawbacks associated with a conventional VTOL kit such as being burdened by weight and drag from the VTOL kit's rotors/propellers, mounting hardware, etc. during a mission which otherwise would limit the fixed-wing aircraft's maximum airspeed, ceiling, payload capacity, endurance, and so on.

Abstract

A separated lift-thrust (SLT) aircraft includes a longitudinal-thrust engine and articulated electric rotors, at least some of which are variable-position rotors having variable orientations based on rotor position signals. Control circuitry independently controls thrust of the longitudinal -thrust engine and the thrust and orientation of each of the variable-position rotors, relative to the aircraft lifting surface and longitudinal thrust engine, to provide for commanded thrust-vectoring maneuvering of the aircraft during VTOL, fixed wing flight, and intermediate transitional states, including maintenance of a desired pose of the lifting surface independent of orientation of the rotor orientations when hovering the aircraft in windy conditions. A flight and navigation control system automates flight maneuvers and maintains desired aircraft pose and position relative to static or dynamic coordinates during station keeping, tracking, avoidance, or convergence maneuvers.

Abstract

A method for forming temporary protective coatings and bondable surfaces is disclosed. In the method, a soluble layer (32) is disposed on a material surface, such as the interior surfaces of cell walls (24) of a web material (16). The soluble material (32) is then removed or leached from the web material to form and expose a roughly textured (36), bondable surface for bonding with another material, such as AVCOAT insulation (26). Use of the soluble layer (32), therefore, enhances the bondability of any surface that requires good adhesion, such as where the surface is difficult to reach for conventional surface preparation techniques.

Abstract

A heterodyne receiver includes first and second laser sources (e.g., laser diodes) which generate optical receiver oscillator (RO) signals having respective RO frequencies. Temperature control circuitry controls a temperature difference between the operating temperatures of the sources such that the RO frequencies differ by a difference frequency corresponding to the temperature difference, the difference frequency being offset from a frequency of a modulated millimeter-wave signal by a predetermined intermediate frequency. An electro-optical nonlinear mixer (e.g., a photodiode) receives the optical RO signals and the modulated millimeter-wave signal and generates an electrical intermediate-frequency (IF) signal, which is provided to an electrical amplifier/detector to detect the output signal corresponding to the modulation of the modulated millimeter-wave signal. The receiver may form part of a heterodyne transceiver having a transmitter which employs an optical heterodyne structure for generating a millimeter-wave signal for transmission.

Abstract

A surveillance system is configured to detect a rotary-wing aircraft approaching a facility and provide a warning upon detection. The system includes acoustic processing nodes that receive acoustic signals from the environment surrounding the facility. As the nodes receive the acoustic signals, the nodes perform a spectral analysis of the signals to detect if the source of the acoustic signals is a rotary-wing aircraft. Additionally, based upon the acoustic signals, the nodes detect an altitude of the rotary-wing aircraft and a distance between the rotary-wing aircraft and the facility. In the case where the system identifies the rotary-wing aircraft as encroaching a predefined geographical area outside of the facility, based upon the altitude and distance between the rotary-wing aircraft and the facility, the system generates a warning to allow security forces to intercept the rotary-wing aircraft prior to its arrival at the facility.

Abstract

A technique for processing an electronic apparatus (e.g., manufacturing an assembled circuit board, treating an assembled circuit board, etc.) involves applying encasement material to an area of the circuit board assembly while leaving at least a portion of the circuit board assembly exposed. The technique further involves causing the applied encasement material to harden (e.g., heating the encasement material in a curing oven, applying radiation, providing a chemical catalyst, etc.). Application and hardening of the encasement material may take place shortly after circuit board assembly (e.g., by automated equipment at a manufacturing facility in order to treat newly assembled boards) or at some later time in the field (e.g., by a technician servicing a legacy board).

Abstract

A deployable stationary device includes a device support, rate gyros supported by the device support, the rate gyros being oriented along different axes, and a controller supported by the device support. The controller is arranged to receive rate gyro signals from the rate gyros. Each rate gyro signal indicates a rate of rotation about a respective axis associated with a particular rate gyro. The controller is further arranged to perform a vector sum operation based on the rate gyro signals, and generate a direction signal which identifies a direction resulting from performance of the vector summing operation. Such a deployable stationary device is capable of operating as one of a network of such devices in a surveillance system to enable detection and precise location of suspicious activity.

Abstract

A technique provides a remote adjustment to a portion of an airplane engine (20). The technique involves attaching a remote adjuster (24) to the portion of the engine (20) at a proximate location (52) to the engine (20) while the engine is not running. The portion is configured to receive a direct manual adjustment from a user while the engine (20) is running and while the user is in direct physical contact with the portion. The technique further involves, after attaching the remote adjuster (24) to the portion of the engine (20), supplying user input to the remote adjuster (24) at a distal location (56) to the engine (20) to provide a remote adjustment to the portion of the engine (20) through the remote adjuster (24) in place of the direct manual adjustment from the user. The technique further involves, after supplying the user input to the remote adjuster (24) removing the remote adjuster (24) from the portion of the engine (20).

Abstract

A dispenser system provides a means to automatically deploy systems using a controlled dispense approach capable of providing desired operational flexibility. Components such as unattended ground sensors (UGS) are deployed according to a method which includes incorporating the components into an elongated ejection system to form a payload assembly, the ejection system including axially-displaced ejector bays each for holding respective components. Each ejector bay retains the respective components until a respective ejection event upon which the ejector bay ejects the components in a radial direction. The payload assembly includes a stabilizer such as a drogue parachute that substantially prevents the payload assembly from rotating about its elongated axis. A timing sequence for the ejection events is programmed into the ejection system to achieve a desired coverage pattern of the components after deployment. The timing sequence can be chosen to result in a coverage pattern along a continuum from maximum component density to maximum total area coverage. The payload assembly is subsequently released from an aerial vehicle above the area with activation of the timing sequence, such that the ejection events occur during flight of the payload assembly at respective times after its release.

Abstract

An optical parametric oscillator (14) includes a source (10) of coherent energetic pump optical signals and an optical resonator cavity which includes a set of optical parametric amplifying (OPA) crystals (20a, 20b) and a set of optical elements (22, 24, 26) such as mirrors disposed along an optical path. The optical elements are configured (1) to direct an oscillation optical signal (28) generated by the OPA crystals along the optical path, (2) to provide input coupling of the energetic pump optical signals (12a, 12b) such that each energetic pump optical signal travels through only one of the OPA crystals to result in a corresponding depleted pump optical signal, and (3) to provide output coupling of the depleted pump optical signals (18a, 18b) to prevent each depleted pump optical signal from traveling through more than one of the OPA crystals. Resonator cavities have multiple-leg configurations, including 'L' and 'U' shapes, and either linear (or standing-wave) or ring architectures. The pump source may employ wavefront division or alternatively amplitude division of a single relatively high-power optical pump beam.

Abstract

Aspects of the present invention are directed to the use of optical gain structures that include alternating layers of gain medium and transparent heat conductors in which the gain medium itself functions as a correction optic. The gain medium changes to an optimum or desired shape because of the thermal changes occurring as the materials of the optical gain structure(s) reach a desired optical output condition.. At the desired optical output conditions, the gain medium conforms to a desired shape. The desired shape may be, for example, that of an optical surface of a transparent heat conductor. By designing the initial shape of the gain medium such that the physical contact with the transparent heat conductor is maximized at the desired optical output conditions, conductive heat transfer between the gain medium and heat conductor(s) is maximized at the desired optical output condition.

Abstract

Amplified spontaneous emission (ASE) ducts (104, 204, 304, 404, 504, 604) are disclosed for use with various gain media. An ASE duct may be configured and arranged to remove ASE from solid state or liquid gain media (102, 202, 302, 402, 502, 602) and transmit the ASE to an exterior optical medium (1). The refractive index of an ASE duct is selected as desired based on the refractive index of a gain medium and an exterior optical medium. An ASE duct may include first and second boundary surfaces joined at a vertex having an included angle that allows ASE (light) reflected off on one boundary surface to be incident on the another boundary surface at less than the critical angle and transmitted outside of the ASE duct. Laser systems using ASE ducts and methods of using and manufacturing ASE ducts are disclosed.
